摘要：The passive optical network system and method for providing a predeterminedwavelength of data to remote users according to the present invention includes amultiple wavelength transmitter for transmitting a multiwavelength signal. Themultiwavelength signal is provided by an access provider and has a plurality of signalcomponents each of predetermined wavelength. A power-splitting passive opticalnetwork receives and power-splits the multiwavelength signal into a plurality ofdistributed multiwavelength signals each associated with a respective remote user. Afilter selectively filters out, for each remote user, ones of the signal components of theassociated distributed multiwavelength signal to provide the remote user with a selectedone signal component of predetermined wavelength.
